Around the Earth, there are only a handful of planets that can reach a state of hydrostatic equilibrium, and in terms of current human technology, the planets that manned spacecraft can and can reach are Mars and Venus except for the Moon. Probes can reach planets far away, such as asteroid belts or planets beyond, but if you want to carry people there, you don't even have to think about it.

It's good to say that even Tang Feng has been on the moon, but the last time he landed on the moon, because the star core was still in a fourth-level state, it couldn't use the dark energy in the universe, so the star core split at that time was helpless against the moon.

Mars is arguably the only planet that humans are most likely to land on besides the Moon. The work that Tang Feng is doing now with a huge amount of money is to prepare for the manned landing on Mars.

Mars has two moons, Phobos and Deimos, but those two moons have not reached hydrostatic equilibrium at all, they are just two irregularly shaped asteroids.

As for Venus, although it is closer to the Earth than Mars, the planet Venus is really not something that humans can climb on. At least not in the current state of science and technology, humans can climb on it.

Although among the eight planets in the solar system, the planet most similar to the Earth is Venus, regardless of size or structure, Venus and the Earth are definitely sister stars. However, the climatic conditions on Venus are too poor, much more extreme than on the Moon.

Although Venus is slightly smaller than Earth, its atmosphere is 100 times denser, which means that on Venus, the atmospheric pressure is 90 times that of Earth, which is equivalent to the pressure at a depth of 900 meters in the Earth's oceans.

Such a great pressure is absolutely unbearable even if the astronauts wear the most advanced anti-compression suits.

In addition, Venus's atmosphere is dominated by carbon dioxide, so on the surface of Venus, high-intensity acid rain often falls that is no less corrosive than sulfuric acid. In contrast, the acid rain that falls on Princess Belle Island as it rises above the surface is simply freshwater than fresh water. Therefore, even if the astronauts can withstand the great pressure to land on Venus, if they catch a shower of sulfuric acid rain, hehe

Taking a step back, even if astronauts can withstand both high-pressure and highly corrosive acid rain, let's not forget that the temperature on the surface of Venus can reach 500 degrees Celsius, and at such temperatures, there is probably no spacesuit that can resist it

High temperature, high pressure, and highly corrosive acid rain are just these three extreme conditions that are enough to limit the current human landing on Venus. No one can stand such extreme conditions on the surface of Venus.

But if you don't land on Venus, do you really want to go to the asteroid belt and land on dwarf planets like Vesta and Ceres? That place is so far away from the earth that even a Martian spacecraft can't fly there

Is it really going to take decades or hundreds of years to accomplish this task?

Tang Feng shook his head, for such a long time, Tang Feng would never be able to wait.

"My dear master, are you in trouble? Why don't you talk to me anymore? The sudden voice of the star core woke Tang Feng from his contemplation.

Tang Feng shook his head with a smile and said, "Star Core, I'm really thinking about some issues right now, I'm thinking about how to send your split body to those eligible planets." You know, at this stage, the technology of our civilization has not yet reached that height, and there are still some insurmountable technical barriers to send your split to an eligible planet."

"My dear master, are you bothered to transport vehicles?" The star core pointed out the source of Tang Feng's troubles for a while.

"Damn, how do you know?" Tang Feng was taken aback. The star core has been upgraded, not only has it become a chatterbox, but it is also a lot smarter.

"My dear master, have you forgotten that you still have a very advanced vehicle in my space?"

The words of the star core immediately reminded Tang Feng of the Nautilus, which he hadn't paid attention to for a long time.

It's a high-tech alien ship that can perform interstellar jumps, and it's just for the owner of the core. When he obtained the spacecraft in the underground space of Vincennes Peak in Antarctica, Andro Anderson. Fan. Old Man Alexander told himself very clearly that only with enough star core energy storage can he exert the true effect of this spaceship.

Well, in the past, the star core relied on the radioactive elements on the earth to accumulate energy, but now the star core has been replaced by absorbing the ubiquitous dark energy in the universe for energy accumulation, compared to the radioactive elements on the earth, the dark energy in the universe can be described as endless.

"Star Core, you mean I can use the Nautilus to go to other planets?" After hesitating for a moment, Tang Feng asked.

"My dear master, that vehicle has been in my space for years, and it would be a great waste if you didn't make use of it. This vehicle is specially prepared for Star Core owners like you, and I can now absorb dark energy for energy replenishment, so my dear master, you don't have to worry about running out of energy when using this vehicle. ”

"Also, my dear master, with the function of this vehicle, let alone you go to any planet in this star system, even if you want to enter the star or fly out of this star system, it will be no problem. And compared to the vehicles you've ridden before, this one is faster than you can imagine, so why don't you use it, my dear master, to fulfill your plans? ”

Of course, Tang Feng wanted to use the Nautilus to drag himself to Venus or the asteroid belt, but that thing really can't show up now. If the Nautilus is shown for no reason, the world will not be able to fry?

However, this proposal of the star core strengthened Tang Feng's confidence in landing on Mars, after all, when he landed on Mars, one of the big purposes was to find a suitable opportunity for the Nautilus to appear in front of the world.

Just like the star core split used to dispose of nuclear waste, it was Tang Feng who used the moon landing operation to find an "extraterrestrial meteorite" on the surface of the moon, which allowed the star core split to appear in front of the world openly.

And if the Nautilus wants to appear, it will naturally have to appear from a more distant planet. Take Mars, for example

After doing the math, it seems that the manned Mars exploration program must be realized first.

"Well, since that's the case, then the matter of upgrading the star core can wait for a while, anyway, landing on Mars and the upgrade of the star core are also inextricably linked, after all, one of the star core splits is to be placed on Mars, everything will wait until after landing on Mars!" Tang Feng secretly made the next action plan. (To be continued.) )
